UserAction.java
// 接收前端发送来的分页参数
private int page = 1;
public void setPage(int page) {
this.page = page;
}
public int getPage() {
return page;
}
private int limit = 2;
public int getLimit() {
return limit;
}
public void setLimit(int limit) {
this.limit = limit;
}
public String findAll(){
List<User> allUser = this.getUserService().findAllUser(this.getPage(), this.getLimit());
Map<String, Object> result = new HashMap<String, Object>();
result.put("code", 0);
result.put("msg", "");
result.put("count", this.getUserService().findTotalRecord(key));
JSONArray array = JSONArray.fromObject(allUser);
result.put("data", array);
// 将其转换为JSON数据,并压入值栈返回
ActionContext.getContext().getValueStack().set("jsonData", JSONObject.fromObject(result));
return "success";
}
struts.xml配置
<!-- 用户配置 -->
<package name="user" namespace="/" extends="common,json-default">
<action name="userAction_*" class="userAction" method="{1}">
<result name="success" type="json">
<param name="root">jsonData</param>
</result>
</action>
</package>
返回JSON数据格式,也是layui数据表格要求的格式
{
"code": 0,
"msg": "",
"count": 15,
"data": [
{
"usersId": "1",
"userName": "user12",
"userEmail": "123@qq.com",
"userSex": "女",
"userStatus": "0",
"userGrade": "倔强青铜",
"userEndTime": "2018-11-11 15:22:33"
},{
"usersId": "2",
"userName": "asd",
"userEmail": "123@qq.com",
"userSex": "男",
"userStatus": "1",
"userGrade": "秩序白银",
"userEndTime": "2018-11-11 15:22:33"
},
......
]
}
注意:
1.js中table的field需要与返回的数据key相对应,比如field: “userName”与“userName”: “asd”
2.layui的数据表格向url发送请求时,会附上page以及limit这两个参数,所以服务端需要接收并以此为条件查找数据
前端展示效果
以上这篇layui之数据表格--与后台交互获取数据的方法就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持脚本之家。
